Building envelope continuity analysis
Check building envelope details for continuity, thermal bridging, and waterproofing. Helonic traces air, water, and thermal control layers across wall sections, roof transitions, window heads and sills, and foundation-to-wall connections to catch the discontinuities that cause building failures.
Why envelope analysis matters
The true cost of envelope failures across the life of a building.
From PDF upload to continuity report
Helonic reads every wall section and detail to trace control layers end to end.
Extract wall sections
The AI reads architectural wall sections, roof details, and building elevation details to identify each control layer: air barrier, weather-resistive barrier, vapor retarder, and insulation.
Trace control layers
Each control layer is traced from foundation to roof, through every transition: wall-to-roof, wall-to-window, wall-to-foundation, and wall-to-wall corners.
Identify discontinuities
The system flags any point where a control layer terminates without a proper transition, where materials change without compatible lapping, or where thermal bridging occurs.
Report with references
Each finding includes the specific detail sheet, the control layer affected, the nature of the discontinuity, and the potential consequence.
What we check
Envelope details where missed transitions become major failures.
Air barrier continuity
Traces the designated air barrier material through every wall section, verifying that it is continuous, properly sealed at penetrations, and connected at transitions between assemblies.
Waterproofing termination
Checks that below-grade waterproofing terminates above finish grade, that through-wall flashing drains to the exterior, and that all laps shed water correctly.
Thermal bridge detection
Identifies structural elements (steel lintels, shelf angles, concrete balcony slabs, steel studs) that penetrate the insulation layer and create thermal bridges that reduce effective R-value.
Flashing detail review
Verifies that head, sill, and jamb flashing at windows and doors is properly integrated with the weather-resistive barrier, with end dams and proper drainage to the exterior.
Window and door integration
Checks that window and door installations are detailed with proper sealant joints, backer rod, flashing integration, and that the air barrier connects to the window frame.
Roof-to-wall transition
Examines the critical transition where roof membrane meets wall assembly, verifying that base flashing height, counterflashing, and membrane termination are properly detailed.
Why this matters
The building envelope is the single most important system for long-term building performance. Envelope failures cause water intrusion, mold, energy loss, occupant discomfort, and structural deterioration. The vast majority of construction defect litigation involves the building envelope, and the costs of remediation regularly exceed the original envelope construction budget.
The challenge is that envelope performance depends on continuity across hundreds of transition details, and a single missed detail can compromise the entire system. Helonic systematically traces every control layer through every transition, catching the gaps that even experienced envelope consultants can miss in a manual review of a large drawing set.
